Hello,

So I am goin to fit a spacer to the 4x4 saph but do I need a 10 or 14 mm one for the fuel rail to sit on the other side?

I have been reading and some say 10 mm but then others said 14 mm.

I know they don't do alot till you have about 400-450 bhp but it can't hurt just fitting one.


Cheers Eigdoog.
